[Material] - Corrosion resistance: Made of ABS plastic, ABS (acrylonitrile-butadiene-styrene copolymer) is known for its excellent chemical corrosion resistance. It can effectively resist the erosion of smoke, oil and various corrosive gases, ensuring continuous and stable operation in various harsh environments. - Durability: ABS material not only has good impact resistance and heat resistance, but also maintains long-term mechanical strength and prolongs service life. [Design features] - 90° elbow design: Compared with right-angle elbows, this design can more flexibly adapt to complex installation environments, reduce space occupancy, while ensuring the smoothness of smoke circulation and avoiding inaccurate monitoring problems caused by airflow obstruction. - Impact on airflow*: The elbow design is designed to minimize the impact on airflow, ensure that the smoke detector can accurately and timely capture smoke signals, and improve the overall sensitivity and reliability…
